13. Daycent Simulation of Methane Emissions, Grain Yield, and Soil Organic Carbon in a Subtropical Paddy Rice System
ABSTRACT The DayCent ecosystem model, widely tested in upland agroecosystems, was recently updated to simulate waterlogged soils. We evaluated the new version in a paddy rice experiment in Southern Brazil. DayCent was used to simulate rice yield, soil organic carbon (SOC), and soil CH4 fluxes. Model calibration was conducted with a multiple-year dataset from

14. Rbio: A tool for biometric and statistical analysis using the R platform
Abstract Rbio is a free software for data processing. It is compatible and integrated with the free R software, which is globally accepted for statistical analysis. Thus, Rbio takes advantage of all processing potential of the R software. However, this new software allows the user to perform all the analyses without knowing the programming in R language. Rbi

15. BALANCING AMBULANCE CREW WORKLOADS VIA A TIERED DISPATCH POLICY
ABSTRACT Emergency Medical Services (EMS) system’s mission is to provide timely and effective treatment to anyone in need of urgent medical care throughout their jurisdiction. The default dispatch policy is to send the nearest ambulance to all medical emergencies and it is widely accepted by many EMS providers. However, sending nearest ambulance is not alw

16. Evaluation of 12 m Long Turned Down Guardrail End Terminal Using Full-Scale Crash Testing and Simulation
Abstract The beginnings and ends of guardrail designs have the function of providing adequate anchorage for the rest of the system. They should also demonstrate crashworthy performance and should not pose any hazard for errant vehicles. In Europe, the ends of guardrail systems traditionally have incorporated turned down end terminals. Due to its low cost, Tu

17. Numerical Simulation on the Radar Cross Section of Variable-Sweep Wing Aircraft
ABSTRACT: The influence of variable-sweep wing on the aircraft's radar cross section (RCS) characteristics has been studied to reduce the aircraft's RCS as well as its detection probability by the hostile radar. With the help of CATIA, a 3-D digital model of the variable-sweep wing aircraft is built to generate a series of digital grids. Using MATLAB, a nume

18. Daily counting of manufactured units sent for quality control: a bayesian approach
This paper presents the statistical modeling for daily counting statistics of units that arrive for quality inspection at a food company. Different Poisson regression models were considered in order to analyze the data collected, with a Bayesian focus. The main objective was to forecast the daily average count based on co-variables such as days of the week.

20. Uncertainty mitigation through integration with history matching and sampling techniques / Mitigação de incertezas através da integração com ajuste de histórico de produção e técnicas de amostragem
As incertezas geológicas influenciam diretamente a previsão de comportamento de reservatórios de petróleo, podendo, muitas vezes, tornar mais complexo o uso de ferramentas como simuladores de fluxo. A integração de técnicas de redução de incertezas e ajuste de histórico ganha um importante destaque neste processo, principalmente devido às limitaç

21. O uso de quase U-estatísticas para séries temporais uni e multivaridas / The use of quasi U-statistics for univariate and multivariate time series
Classifcation and clustering of time series are problems widely explored in the current literature. Many techniques are presented to solve these problems. However, the necessary restrictions in general, make the procedures specific and applicable only to a certain class of time series. Moreover, many of these approaches are empirical. We present methods for

24. Asymmetric information in brazilian private health insurance market: testing the benefice of coinsurance plans / Assimetria de informação no mercado brasileiro de saúde suplementar: testando a eficiência dos planos de cosseguro
Asymmetric information in the health care system is a topic of interest for medical insurance, policy makers and scholars. This research analyses how the contracts of coinsurance motivate the moral hazard and adverse selection phenomenon and consequences in medical services demand. In this context, the analysis of asymmetric information in the health care sy
